Yes, you can RAID a SSD and a HDD, but you never should.
A RAID array’s performance is based upon the drive with the slowest Read/Write speeds.
If you created a RAID array with a SSD and a HDD it would be a waste of the SSD’s capability.
A RAID array’s capacity is also based upon the drive with the smallest capacity.
If you RAID-0 a 60GB drive and a 240GB drive your array will only be 120GB (60GB x 2) in size.

Identical drives should be used in any RAID array for maximum performance.

second can u do partial raid like having 1 ssd not in raid then 2 hd's in raid 1 or 0 or even a hd and then 2 other hd's in raid 1 or 0 or another example where u have 1 ssd then 4 hd's in raid10 or again 1 hd and 4 hd's in raid 10. said:

Yes, this can be done. When you create your RAID array in the RAID BIOS you have to manually select which drives will be part of the array. So if you have 4 HDDs and 1 SSD connected to your motherboard you could go into RAID BIOS and create a RAID-1 array and select 2 HDDs to be part of the array, save your settings, create a RAID-0 array and select the 2 remaining HDDs to be part of that array.

Remember to have a backup plan with any RAID-0 array. If any drive in the array fails you will lose all data in the array.
